You can contact Pompanette direct and get just the lense. Be sure to have the dimensions of the hatch and the Maxum part number so you get the correct one. You can also usually choose between white or tinted lense. You will also need to order a new gasket. The process is relatively straight forward to replace. You will need to completly remove the hatch (only the moveable part, not the frame mounted to the boat), use a razor to cut through the silicon selant that bonds the lense to the frame, and then you can pill the old lense and gasket out. You need to do a thorough job of cleaning the frame to remove all traces of the old silicone, then you cut the gasket material to fit, apply the new silicone sealant and set the new lense in place. I usually set something realatively heavy (50 lbs) on the lense to ensure is sits nice and square in the frame while the silicone cures. I have done 2 of these and they turned out great.
